Abstract: A reference signal (RS) transmission system to transmit a channel state information (CSI) RS for extraction of CSI to a relay and a macro terminal is disclosed. The base station transmits information on a sub frame containing the CSI RS to the relay or the macro terminal. The macro terminal and the relay receive the CSI RS using the information on the sub frame. The macro terminal and the relay extract the CSI using the CSI RS and transmit the extracted CSI to the base station.

Abstract: The present application relates to a method of generating a downlink frame. The method of generating the downlink frame includes: generating a first short sequence and a second short sequence indicating cell group information; generating a first scrambling sequence and a second scrambling sequence determined by the primary synchronization signal; generating a third scrambling sequence determined by the first short sequence and a fourth scrambling sequence determined by the second short sequence; scrambling the short sequences with the respective scrambling sequences; and mapping the secondary synchronization signal that includes the first short sequence scrambled with the first scrambling sequence, the second short sequence scrambled with the second scrambling sequence and the third scrambling sequence, the second short sequence scrambled with the first scrambling sequence and the first short sequence scrambled by the second scrambling sequence and the fourth scrambling sequence to a frequency domain.

Abstract: A method for transmitting and receiving signals for ultra reliable low latency communication. A method of operating a terminal includes: receiving, from a base station, first DCI including resource allocation information of a first PDSCH; performing a blind decoding operation on a PDCCH candidate when a resource region of the first PDSCH indicated by the first DCI overlaps with a resource region of the PDCCH candidate; and performing a receiving operation of a downlink channel on the basis of a result of the blind decoding operation. Therefore, the performance of a communication system can be improved.

Abstract: A method and an apparatus for uplink transmission in a communication system. An operation method of a terminal includes: receiving, from a base station, first SFI information indicating n flexible symbol(s); receiving, from the base station, second SFI information re-indicating m symbol(s) of the n flexible symbol(s) as uplink (UL) symbol(s); and transmitting an SRS to the base station through the m symbol(s) re-indicated as a UL symbol among the n flexible symbol(s) indicated as a flexible symbol. Therefore, performance of the communication system can be improved.

Abstract: Disclosed is a method for signaling control information for coordinated multipoint (CoMP) transmission in a wireless communication system. The control information signaling method for CoMP transmission is performed by a base station and comprises providing, through RRC signaling, a terminal with setup information on each CSI-RS resource of a CoMP measurement group which is set in the terminal; and selectively providing, through DCI, the terminal with control information which indicates mapping of the PDSCH resource element corresponding to terminal and at least either pseudo-same positionality information of CSI-RS or pseudo-same positionality information of DM-RS. Thus, control information signaling for coordinated multipoint transmission can be efficiently performed.

Abstract: A base station divides a subframe into a downlink time duration for downlink, an uplink time duration for uplink, and a guard period between the downlink time duration and the uplink time duration. The base station transmits a downlink control channel including information on a downlink packet duration allocated for downlink transmission of a terminal and information on an uplink packet duration allocated for uplink transmission of the terminal to the terminal in the downlink time duration.
